the answer is 6
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7
2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
n + 13 = 21. n = 21 - 13
The value of n is 3, by the commutative property.
the answer is 6
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7
n = 8
2n plus 7 equals 19 2n equals 12 n equals 6
2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
7 + n = 14 n = 7
n + 13 = 21. n = 21 - 13
The value of n is 3, by the commutative property.
n=13
If n + 7 = 12, then n = 12 - 7
n + 7 = 10subtract 7 from both sidesn = 3
n + 5 = 18 n = 13
